高电阻率收尘极板有利于收集低比电阻粉尘的理论分析

高电阻率收尘极板是指收尘极板的电阻率远远大于金属极板的极板，能很好地防止因烟气中的有腐蚀的物质而使极板受到腐蚀，在相同的条件下，从高电阻率极板上粉尘层的电荷释放方程来看，高电阻率收尘极板增加了电荷释放的时间，从而有利于收集低比电阻粉尘，试验时测得，金属板对碳黑粉尘收集效率为24．72％，高电阻率极板对碳黑粉尘收集效率为71．96％。

山东荣成月湖浮游动植物的研究

对山东荣成月湖水中的浮游动，植物种类、数量及分布变化进行了研究。采用浅水浮游生物网自水底至水表面采集浮游动、植物，样品经固定后称重、计数及初步分类，同时进行各采样点的水质采集及分析。水质检测结果显示月湖水质的酸度正常，重金属、磷、总无机氮、溶解氧符合一类水质标准，COD属于三类水质标准。浮游植物统计结果表明，靠近人海口的站位9#其浮游植物最为丰富多样，其它站位的浮游植物则较少。在总共检出29种浮游植物中，优势种占6种；浮游动物检出22种，其中优势种占6种。研究结果与1982年荣成南部靖海湾的调查结果(浮游植物26种，浮游动物18种)相比，其浮游生物种类与数量有所提高。     

用IPv6建设移动电子商务的方法

当前，移动电子商务发展迅速，但原有的互联网协议IPv4已无法适应这种发展。IPv6作为下一代互联网络协议，在地址空间，安全性、移动性方面有着IPv4难以比拟的优势，而且IPv6能兼容多种移动互联技术，从而能够适应移动电子商务的发展需求，用IPv6是建设移动电子商务的一个很好的选择。

Mineralogy of clean coal combustion by-products

Coal combustion technologies are changing in order to burn coal more cleanly. Many “clean combustion“ and postcombustion technologies are developed to remove SO2 and NOx gases, particulate matter during combustion, or from the flue gases leaving the furnace. This paper focuses on three types of fly ash (flue gas desulfurization (FGD) residuals, atmospheric fluidized bed combustion (AFBC) residuals and sorbent duct injection (SDI) residuals) which produced by “the clean combustion“ and postcombustion technologies. The residuals formed by FGD are PCFA (pulverized coal fly ash) grains entrained with reacted and unreacted sorbent and have lower bulk densities than PCFA grains because it contains higher concentrations of calcium and sulfur, and lower concentrations of silicon, aluminum and iron than PCFAs. AFBC residuals consist of spent bed which is a heterogeneous mixture of coarse-grained bed material and irregularly shaped, unfused, spherical PCFAs. The main crystalline phases in AFBC residuals are anhydrite (reacted sorbent), quartz and lime (unreacted sobent), calcite, hematite, periclase, magnetite and feldspars.The residuals produced by SDI contained 65%-70% PCFA with the larger sizes material being irregularly shaped, fused or roughedged. The reaction products of sorbent (portlandite and lime) included calcium sulfate (anhydrite) and calcium sulfate. The chemical properties of these residuals are similar to those of high calcium PCFAs because of the high alkalinity and high pH of these residuals.
